Plastic injection moulding for defence technology

Precision and reliability for demanding missions

Compromises are not an option in defence technology. Every part and every component must function reliably under the most extreme conditions and meet the highest safety standards. LANGER is your experienced partner for high-precision and extremely robust plastic components that are specially developed and manufactured for the critical requirements of the defence and security industry. You can rely on our in-depth expertise and solution-orientated approach to successfully implement your complex projects.

Why plastic injection moulding is indispensable in defence technology

Modern defence technology places the highest demands on materials and production. High-performance plastics, manufactured precisely by injection moulding, offer decisive advantages over traditional materials:
  • Weight saving & mobility: Lightweight plastic components reduce the overall weight of equipment and systems - a critical factor for mobility, range and transport capacity in military applications.
  • Extreme resistance: Our specially selected polymers withstand extreme temperatures, aggressive chemicals, UV radiation, vibrations and shocks. They therefore guarantee unrestricted functionality under the toughest operating conditions.
  • Corrosion resistance & durability: Unlike metals, plastics are immune to corrosion. This significantly extends the service life of components and minimises maintenance costs - essential for reliability in the field.
  • Design freedom & function integration: The plastic injection moulding process enables the realisation of complex geometries and the integration of several functions in one component. This reduces assembly work, the number of components and therefore costs.
  • Specific electrical properties: From precise electrical insulation to effective electromagnetic shielding (EMI/RFI), plastics offer a wide range of options for optimising electronic systems in defence technology.
  • Vibration damping & noise reduction: By using suitable polymers, we can develop components that dampen vibrations and reduce noise, which improves the ergonomics and camouflage capability of systems.
  • Cost efficiency: Particularly in series production, plastic injection moulding offers an economical alternative to other manufacturing processes without compromising on performance or reliability.

Material expertise for the highest demands

The image features a stack of rectangular blocks labeled with the names of different materials: PEEK, PEI, PPS, PSU, and LCP.
Choosing the right material is crucial for the performance of the end product. We provide comprehensive advice on the selection and processing of high-performance polymers and special engineering plastics. Our in-depth knowledge covers a wide range of properties: from extreme impact resistance and flame retardancy to radar transparency/absorption and ESD protection. Together we will find the optimum material solution that exactly matches your specifications and application conditions.

Fuel lines, hydraulic components, pneumatic systems, housings for sensors, flexible lines and hoses, components in contact with media or in environments with moisture, where dimensional stability is critical.

Precision in detail: from toolmaking to series parts

Our core competence lies in the development and production of injection moulds that are designed for maximum precision and reproducibility. This is the basis for plastic components that fulfil even the tightest tolerances - essential for critical functional components in defence technology. We guarantee consistent, top quality throughout the entire series, from prototype to mass production, thanks to our modern manufacturing processes and stringent testing procedures.
Our tolerance management is particularly noteworthy: we understand the importance of tight shape and position tolerances and use the latest manufacturing and measuring technologies to ensure that these are consistently adhered to. Our in-house toolmaking department guarantees the precision and durability of your components and also enables rapid iterations and adjustments during the development phase.

FAQ about plastic injection moulding in defence technology

Which plastics are particularly suitable for military applications and why?
High performance polymers such as PEEK, PPS, PEI, PSU, LCP, glass or carbon fibre reinforced polyamides and special TPU grades are suitable for military applications. These materials offer properties such as high impact resistance, extreme temperature resistance, inherent flame retardancy, excellent corrosion resistance and often the possibility of EMI/RFI shielding, which are essential for robustness and reliability in defence technology.
How does LANGER guarantee the precision and reliability of plastic components for critical applications?
We attach great importance to maximum precision in our own mould construction and production. By using state-of-the-art injection moulding machines, optical measuring methods and strict quality management in accordance with ISO 9001, we ensure that every component complies with the tightest tolerances and is absolutely reproducible throughout the entire series. Our understanding of processes and our experience are focussed on safety-critical areas.
Can plastic injection moulded parts contribute to weight savings in defence technology and what effect does this have?
Yes, significantly. High-performance plastics are much lighter than metals and still offer excellent mechanical properties. This enables considerable weight savings in equipment, systems and vehicles, which has a positive impact on mobility, range, transport capacity and ergonomics for personnel.
How does LANGER handle sensitive and secret project data from defence technology?
Absolute discretion and confidentiality are a matter of course for us and a fundamental prerequisite for collaboration in defence technology. We implement strict internal security protocols and are always ready to sign comprehensive confidentiality agreements to fully protect your sensitive project data.
What role does the choice of material play in resistance to extreme environmental influences?
The right choice of material is crucial for resistance to extreme environmental influences such as high/low temperatures, UV radiation, moisture, chemicals and vibrations. We provide you with comprehensive advice and select materials that are optimally adapted to the specific operating conditions and the required standards of your application to ensure durability and functional reliability.
Does LANGER also offer support in the development and prototyping of defence technology components?
Yes, we see ourselves as a fully-fledged development partner. We support you from the initial idea through design optimisation, material selection and feasibility studies to rapid prototyping and sampling. Our co-engineering approach and the use of simulation tools help you to accelerate your product development efficiently and with low risk.
